There are a few tried and true ways of getting a death glare from a pregnant lady.
Want a death glare from me? It’s really very simple to get one.
Make a comment, any comment at all, about what I’m eating. For example:
“You’re eating cereal.” —> Death glare.
“Are we out of potato chips?” –> Death glare.
“I thought your doctor said …” –> Death glare.
“Have you been drinking enough water?” –> Death glare.
There you go. Any of those will work, or you can get creative and come up with your own.
